Hey, welcome to Stuff to Blow Your Mind.

We have another vault episode for you.

This is going to be part four of four in our Hunters of the Dark Ocean series.

This one originally published 4-1 2025. Let's get deep. Let's get weird. One last time.

Welcome to Stuff to Blow Your Mind, a production of IHeart Radio.

Hey, welcome to Stuff to Blow Your Mind.

My name is Robert Lamb.

And I am Joe McCormick, and we're back with part four in our series on Predators in the Deep and Dark Parts of the Ocean.

Now, if you're new to the show or new to the series, as usual, we would recommend you go back and start with part one of the series called Hunters of the Dark Ocean, Part 1, and listen through to catch back up and then return to meet us here once again. But also, if you just want to start here, that's fine. This isn't one of those where it's absolutely crucial to take them in order. But for a brief recap of previous episodes, we talked about how the ocean can be thought of as having different environments

or zones stacked vertically on one another, which according to their depth, have different

conditions. Closer to the surface, of course, there's more warm,

less pressure, more access to sunlight for phytoplankton to feast on, and thus more access to food

all the way up the chain. And then as you go deeper, the waters get colder, darker, pressure

goes up, food resources become more scarce, or at least less dense. And what this means is that much

like how terrestrial animals are evolved to live in one type of an environment and not another,

marine organisms are usually adapted not just to the ocean or seawater, but to a specific

zone of the ocean.

So kind of like how you're not going to find jaguars living in the middle of the Sahara.

You don't find the frosted flatwood salamander in the Midwest prairie.

You also don't find, you know, tuna living in deep ocean trenches like 8,000 meters down.
